I've been happy with My Klipsch earbuds, but they seem to be having issues so I'm thinking about replacing them (they might be S4s, but I'm not sure, they're at least 12 years old). Any suggestion for new (wired) earbuds in the $50-$100 range? I'm not super concerned about high audio quality, but I'd prefer some that can handle my workout music (e.g. Shadows Fall, Killswitch Engage, Metallica) reasonably well. I'd be willing to go over $100 if need be.
